i Specification of Letters Patent.

To all whom z' may concern.'

Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county oi New London and Statev ,of Connecticut, have 'invented a new and usefullmprovement in Printing-Presses, of which the following is a speciication.

The object of 'this invention 'is to provide mechanism for feeding slip sheets into position tO be combined with the printed sheets as they are delivered. This invention is. shownl in connection with n multicolor printing press provided with a. reciprocating delivery, but it is olovious that the invention could be applied in connection with priliting presses of other types and in connection'with sheet deliveries of various types. y A practical embodiment of the invention is Arepresented in the accompanying draw'- ings in which, p

Figure 1 is a part diagrammatic and part longitudinal central section `,through so much of e multicolor printing press as will give a clear understanding of the location, construction and operation of the invention. Fig. 2 is an enlarged detail section,

showing the operative connections between the several parts at one side of the machine. Fig. 3 is an enlarged detail view, showing the operative connections between the several parts at the other side of the machine. Fig. 4 is a detail side lview of the cam which controls the mechanisms'for openingand -closing the grippers on the main sheet feed cylinder and for opening Aand closing the.,

grippers On the slip sheet feed cylinder, and Fig. 5 is asimilar view of the mechanisms for Openinggnd closing the grippers on 'the' slip sheet' cylinder.

The impression cylinder 1l is pro'yidediwith a Aset of grippers 12 arranged to be opened at the proper time in the usual manner, by the stationery cam 'iii-'thor receiving the sheets from the grippers '14 on the meinsjhet. feed cylinderjlyff'fhias cam also .o ens the grippers 12 tthe properY time' to de iverthc maip sheets from .the impression cylinder'- denoted. by 1, ni'

to receive a printed sheet fromthe gripper-s 16 of the first transfer cylinder, and third, to permit the two superposed sheets to be fed to a sheet delivery device` that shown herein being a reciprocating flat sheet delivery device 26, of well known and alpproved form. The upper and lower guides for this reciprocating tiet sheet delivery deviceare denoted by 27, 28, the inner ends of which guides are located in close proximity to the second transfer roll 22.

The mein sheet yieed table is denoted hy 29 and the slip sheet feed table is denoted -by 30. A sheet stop 31 is provided for the table 29 and e sheet stop 32is provided or the table 30.

A stud shaft 33 ismounted in the end' freine l, which stud `shaft may be driven et the desired speed from any suitable source of power, not shown herein. rlhe impression cylinder 11 is provided with a spur gear -ixed thereon and a loose spur gear B, Which loose gear is driven by a spur gear 35 iXed to the shaft 33. The main sheet feed transfer 'cylinder 15 is driven from the impression'cylinder 11, through the spur gears 84, rlvhe iirst transfer reel 17 isdriven from the impression cylindervll, through the gears 3d, 37. The Vsecond transferred 22 is driven from the shaft 33'y through the spur gears 35, The slip sheet 'feed cylinder 25'is 'driven from the second transfer reel 22, through the spur gears 39, 40. The sheet forwarding roll 41 is driven from the second transfer reel 22, through the spur gears 39:', d2. 'The 46 is driven'irom the shaft, through the spur gears 4in?, "The cani-shaft 48- is ,.driven' from the second trspser Areel 22, jthroughthe spi'ir gears 38,9. "The slip sheet-feed" roll "Which-:celeste withv the said cam being 'also arranged to open the grippers 16 for transferring the sheets from the first transfer reel 17 to the grippers 23 of the second transfer reel 22.

A ixed cam 53 is arranged to open the ippers 23 on the second transfer reel 22, dist for receiving a sli sheet from the grippers 24 on the cylin er 25, and second for receiving a printed sheet from the grippers 16 on the first transfer reel 17. A fixed cam 54 is arranged in position to open the grippers 23 for permitting the superposed printed sheet and slip sheet to loe fed to the sheet delivery device 26. y

The mechanisms for controlling the opening and closing of the grippers 14 on the main sheet feed cylinder 15 and the grippers 24 on the slip sheet feed cylinder 25 are controlled from a cam 55 on the impression cylinder shaft 10, which mechanisms are constructed, arranged and operated as follows: The shafts of the grippers 14, 24, are respectively provided with tumblers 56, 57, to which are applied springs 58, 59. These tumblers 56, 57, are operated upon at the proper times by being carried by the revolution of their cylinders 15, and 25, over pins 60, 61and 62, 63, respectively attached .to

the opposite ends Aof levers 64, 65, which work on fulcrum pins 66, 67. These pins 60, 61 an'd 62, 63 are movable by said levers 64, 65, into andout of the path of the tumblers 56, 57 respectively. The lever 64 is rocked at e pro er times by a lever 68 mounted on the fu crum pin 69, one arm of which lever 1s engaged With the cam 55. The lever 4is similarly rocked at' the proper times by a lever 70 mounted in suitable bearings 7l, 72, one arm of Which lever is engaged with the said cam 55. The parts are so timed with respect to each other that the grippers 14 on the cylinder 15 and the grippers 24 on the cylinder' 25, will be opened to receive their respective main sheets and slip sheets every two revolutions `of thesemcylinders, which is every revolution of the impression cylinder 11. The parts are also so timed that the grippcrs 14 will be opened to deliver the Amain sheets to the grippers 12 on the impression cylinder 11, every two revolutions of the cylinder 15. The grippers 24 will also be opened every two revolutions of the cylinder 25 for delivering the slip sheets to the grippers 23 on the second transfer reel 22. f

A cam 7 3 on the shaft 48 controls the operation of the stops 31, 32, as follows: A spring-pressed rocking lever 74 is pivoted arrangement of printing mechanism nerr/,aia

at 75, which lever is provided with a stud 0r roller 76, engaging the cam 73. A rod 77 connects the lever 74 With an arm 78 `fixed to the shaft 79 of the stop 31. Another' A sheet guide 86 is mounted on a crossi bar v87, which sheet uide is located in position to guide the printed sheets around the rst transfer reel 17. Another sheet guide 88 is mounted on a cross-bar 89 in position to direct the slip sheets from the cylinder 25 to the second transfer reel 22.

It is to be understood where the terms cylinder or reel are used, that I intend to cover any operative device for carrying the sheets through the prescribed paths. It is also evident that various changes might be resorted to in vthe construction, form and the several parts Without departing from the spirit and scope of my inventi n. In operation,

the sheets to be printed are fed from the table 29 to the cylinder' 15.

and are fed therefrom to the impression cylinder 11. After the sheet has been printed, it is delivered from the impression cylinder l1 to the rst transfer reel 17. In the meantime a sli sheet has been fed to the cylinder 25 and, this cylinder 25 will feed the slip sheet to the second transfer reel 22 just before the printed sheet is fed thereto from the first transfer reel 17. This second transfer reel Will then transfer the slip sheet together With the printed sheet on top of the same to the sheet delivery device in position to be delivered to any predetermined point.

An automatic means is thus provided for feeding slip sheets into position to be associated with the printed sheets as they are delivered from the printing mechanism.

The parts shown and described but not claimed herein, form the subject-matter of my co-pending application filed June 4, 1910, Serial No. 564,997, of which this is a division.

vWhat I claim is:

A sheet delivery device arranged to deliver the sheets printed side up, a sheet including an impres- 's1on cylinder arranged to receive and deliver one sheet vat each revolution of the cylinder, a printed comprising tvvo reels, one arranged to receive the printed sheet directly from the impression cylinder and transfer it to the as my invention, I have signed my name in second reel and the other arranged to trunspresence of tWo Witnesses, this first day of fer the sheet to the delivery device, and v:1 February A.
